> > > About Chamfer Types and References

The types of placement references that you select determine the types of chamfers that you can create. The following list shows each reference type, and lists the chamfer types that you can create using that reference type:
Edges or edge chains
Select one or more edges or edge chains.
Only edges (solid or a two-sided surface) are valid chamfer references.
An edge chamfer removes the flat section of material from a selected edge to create a beveled surface between the two original surfaces common to that edge. The chamfer propagates across tangent neighbors until it encounters a break in tangency. However, if you use a One-by-One chain, the chamfer does not propagate across tangent neighbors.
Chamfer type: Edge
Examples
Two edges
1. Edge references
2. Chamfer pieces (with distance value)
Edge chain
1. Edge chain reference
2. Chamfer piece (with distance value)
3. Existing round geometry
One surface and one edge
Select one surface first, and then one edge.
The chamfer remains tangent to the surface. The edge reference does not maintain tangency.
Chamfer type: Surface to edge
Example: Surface and edge
1. Surface reference
2. Edge reference
3. Chamfer piece (with distance value)
Two surfaces
Select two surfaces.
The edges of the chamfer remain tangent to the reference surfaces.
Chamfer type: Surface to surface
Example: Two surfaces
1. Surface references
2. Chamfer piece (with distance value)
Vertex and three distance values
Select one vertex reference, and specify three distance values along the three edges that define the vertex.
A corner chamfer removes material from the corner of a part, creating a beveled surface between the three original surfaces common to the corner.
Chamfer type: Corner
Example: Corner
1. Corner chamfer
